Analysis of signals from the DecaWave TREK1000 wideband positioning system using AKRS system

摘要

Ultra-Wideband (UWB) technology completes available technologies of fast data links on short distances and brings new possibilities, e. g. clear identification and possibility to locate each active element in space precisely. Usual applications include various types of precise positioning systems or radiolocation display systems, however, transferring images in very high definition is also expected. One of the leaders in UWB technology production is DecaWave which provides an integrated solution (e. g. DW1000 integrated circuit) and many ready-made implementation solutions. This article was created to help to verify measuring methods and UWB signal analysis using available technology and testing AKRS (Radiosignals Analysis and Classification) system features to use these signals. The result consists of graphs of actually measured curves of analysed quantities which have not been published to this extent yet. They include spectral and time analyses; modulation type, framing and data conversion to bit content are explored. When procedures to measure and analyse UWB DecaWave TREK1000 system radio signals were tested, specific characteristics emerged out of usage of these systems. Catalogue values specified by the manufacturer were verified during the analysis and many other facts that could not be looked up otherwise were determined.
